build fails - lua_objlen

[andmarti1424]

Hello. I am getting this
Building CXX object CMakeFiles/stratagus.dir/src/network/netconnect.cpp.o /home/mongo/src/stratagus.wargus/stratagus/src/network/netconnect.cpp: In lambda function: /home/mongo/src/stratagus.wargus/stratagus/src/network/netconnect.cpp:1882:26: error: ‘lua_objlen’ was not declared in this scope; did you mean ‘lua_rawlen’? 1882 | auto i = lua_objlen(l, -1) + 1; | ^~~~~~~~~~ | lua_rawlen make[2]: *** [CMakeFiles/stratagus.dir/build.make:1880: CMakeFiles/stratagus.dir/src/network/netconnect.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:142: CMakeFiles/stratagus.dir/all] Error 2 make: *** [Makefile:136: all] Error 2

Is this a lua issue?
I have both lua 5.1 and lua5.2..
Thanks.

It looks like your build is running against Lua 5.2, where this function no longer exists. Can you make sure you are using 5.1?

[andmarti1424]

I see. Its there a way to force it use v 5.1?

I think you can set LUA_INCLUDE_DIR and LUA_LIBRARIES, but I don't actually know

[andmarti1424]

This worked for me: cmake -DLUA_INCLUDE_DIR=/usr/include/lua5.1
